Kurdish rebels detonated a roadside bomb as two minibuses carrying army personnel passed on Sunday, wounding 12 soldiers, the private Dogan news agency reported. The attack occurred near the town of Eruh in southeastern Siirt province, the agency said. Military helicopters ferried the injured to a local hospital as troops backed by helicopter gunships launched an operation to hunt down the rebels in the area, it added. Kurdish rebels have killed about 80 soldiers since January, most in roadside bomb attacks on military vehicles.
